Governor Ridge declared a drought emergency in 55 of the 67 counties of Pennsylvania following extended dry weather through much of the summer. Water usage was restricted. Precipitation deficits for many counties for the months of May through July averaged between 5 and 7 inches. Precipitation departures for the 365 day period ending in mid-July were over 1 foot below normal in many places. This is about one-third of total annual normal precipitation in most areas. Streams were empty, wells dried up, and the Susquehanna River hit record low flows. Hot sunny days combined with the dry weather to take a large toll on crops. Preliminary estimates by the Department of Agriculture indicated possible crop losses in excess of $500 million. The figure did not include a 20% decrease in milk production due to the drought that would also result in million dollar losses. There were some counties that experienced 70 to 100% crop loss. At least 30% losses are needed for a drought disaster declaration.
